Description

Technical Field

[0001] This utility model relates to the field of laser spot welding technology, specifically to an auxiliary device for laser spot welding machines. Background Technology

[0002] The laser spot welding machine mainly consists of a laser, power supply and control system, cooling system, light guide and focusing system, and binocular stereomicroscopic observation system. It has a compact structure and small size. The microscopic coordinate indicator, coaxial with the laser beam, facilitates workpiece positioning without the need for special fixtures. Laser power, pulse frequency, and pulse width can all be preset and changed via the control panel. The power supply uses a drawer-type structure for easy removal, making the equipment convenient to operate and maintain.

[0003] Existing laser spot welding machines have a small, liftable spot welding platform installed in the welding chamber to facilitate placing the weld point at the laser exit. However, the actual position of the weld point is uncontrollable and requires frequent adjustments by the operator. While the operator holds the platform on both sides, there is a large area of ​​suspension in the front and back directions, affecting the stability of the weld point. At the same time, when holding the platform, the operator's hands are suspended in the air for extended periods, which can easily lead to fatigue. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the present invention, a laser spot welding machine welding auxiliary device includes a lifting frame 1, a spot welding table 2, and an auxiliary support frame 3. The lifting frame 1 includes a scissor bracket 102; the spot welding table 2 includes a base plate 201, the bottom of which is hinged to the upper end of the scissor bracket 102; the upper surface of the base plate 201 has limit grooves 202 on both sides of its upper surface, the limit grooves 202 are slidably engaged with limit sliders 203, and the limit sliders 203 are fixedly connected to both sides of the bottom of a movable worktable 204; the auxiliary support frame 3 includes two additional plates 301.

[0025] Specifically, the overall auxiliary device is fixedly installed in the spot welding chamber of the laser spot welding machine. The workpiece and electronic components to be spot welded are placed on the upper surface of the movable worktable 204. After adjusting the welding point of the spot welding machine, the movable worktable 204 is controlled to slide back and forth on the upper surface of the substrate 201, so that the front and rear edges of the entire workpiece can be relatively completely mounted on the surface of the movable worktable 204. The left and right edges are held and supported by the operator to facilitate the adjustment of the welding point. At the same time, the operator's hands are supported by the auxiliary support frame 3, providing a point of force, reducing operator fatigue, and improving grip stability.

[0026] Example 1

[0027] like Figure 1-2As shown, in this embodiment, there are two sets of scissor brackets 102. The lower ends of the two sets of scissor brackets 102 are hinged to the inner walls of both sides of the base plate 101, and the upper ends of the two sets of scissor brackets 102 are hinged to the top support bars 103. The two top support bars 103 are respectively fixedly installed on the bottom edges of the base plate 201. A first connecting shaft 104 is rotatably installed at one corner between the two sets of scissor brackets 102, and a second connecting shaft 105 is rotatably installed at the other corner between the two sets of scissor brackets 102. The middle part of the first connecting shaft 104 is rotatably connected to one end of the first lead screw 106 through a bearing. The middle part of the second connecting shaft 105 is screwed to the first lead screw 106. A first knob 107 is fixedly installed at one end of the first lead screw 106.

[0028] In this embodiment, by rotating the first lead screw 106 through the first knob 107, the first lead screw 106 and the second connecting shaft 105 are rotated and twisted together, adjusting the first connecting shaft 104 and the second connecting shaft 105 to move closer or further apart, thereby controlling the two sets of scissor supports 102 to unfold or fold, so as to adjust the actual height of the substrate 201, so that the staff can obtain a suitable field of view from the welding microscope.

[0029] like Figure 3 As shown, in this embodiment, a ceramic tabletop 205 is fixedly installed on the upper surface of the movable workbench 204; a second lead screw 206 is rotatably installed in the limiting slide groove 202; a linkage rod 207 is rotatably embedded on the rear edge of the base plate 201; the rear ends of the two second lead screws 206 and the two ends of the linkage rod 207 are linked to each other through a bevel gear set; the middle part of the linkage rod 207 is linked to the second knob 209 through a worm gear set 208.

[0030] In practice, the ceramic tabletop 205 supports the spot welding operation to cope with the laser. At the same time, the worm gear assembly 208 can be rotated by the second knob 209, and the two second lead screws 206 can be rotated synchronously by the linkage rod 207. The limit slider 203 is rubbed and slides in the limit groove 202 to adjust the actual position of the movable worktable 204, so as to avoid the workpiece being suspended in a large area and affecting the welding stability.

[0031] Example 2

[0032] Based on Example 1, in order to supplement the specific method of supporting the workers' hands with the auxiliary support frame 3, which was not mentioned in Example 1.

[0033] like Figure 1 , 4As shown, in this embodiment, two additional plates 301 are fixedly installed on the two sides of the base plate 101. A base column 302 is fixedly installed on the upper side of the additional plates 301. Adjustment grooves 303 are intersected on both sides of the base column 302. A U-shaped frame 304 is slidably sleeved on the upper end of the base column 302. Fastening bolts 305 are inserted into the adjustment grooves 303 at the lower end of the U-shaped frame 304. A bracket 306 is rotatably installed on the upper end of the U-shaped frame 304. A soft pad 307 is fixedly installed on the upper side of the bracket 306.

[0034] In practice, the worker holds the left and right edges of the workpiece with both hands, places the workpiece on the upper surface of the movable worktable 204, and places the lower edge of the palm on the upper surface of the bracket 306. The bracket 306 can be adjusted to a comfortable height by sliding the adjustable slide 303 on the upper end of the base column 302, and then tightened and locked by the fastening bolt 305. At the same time, the bracket 306 can rotate freely so that the worker's wrist joint can move relatively freely when adjusting the welding point.
